Such states are initiated by inelastic scattering of electrons by nuclei along the path of weak nuclear interaction. The relaxation of such nuclei is also determined by weak interactions. The use of the hypothesis makes it possible to physically interpret a rather large group of experimental data on the initiation of low energy nuclear reactions (LENRs) and the acceleration of radioactive α- and β-decays in a low-temperature plasma. The possible mechanisms of LENRs implemented in a Rossi E-CAT reactor are discussed. It is also suggested that the metastable isu -states of a different type occur as a result of high- energy collisions of particles, when heavy hadrons (baryons, mesons) are formed in the collisions of protons with characteristic energies higher than 1 TeV. This kind of concept makes it possible to + − physically interpret the recently recorded anomaly in the angular e e correlations of positron- electron pairs emitted in the radioactive decays of excited 8Be nuclei formed by the interaction between protons with kinetic energy ~ 1 MeV and 7Li nuclei. A recent hypothesis of the existence of yet another, fifth fundamental interaction by Feng et al, in addition to the strong/weak nuclear, electromagnetic, and gravitational interactions, might be introduced to explain this anomaly. ____________________________________________________________________________________________________ *Corresponding author: E-mail: [email protected]; Serge; PSIJ, 15(2): 1-25, 2017; Article no.PSIJ.34889 Keywords: Metastable non-nucleonic states of nuclear matter; low energy nuclear reactions; heavy hadrons; heavy quarks; inner shake-up state of nuclear matter. 1.

The latter allows one to explain gravitational ones. They were initiated by the why the X boson might have avoided earlier study [3], in which the authors studied the detection.

However, they recorded an nucleus. For these anomalous excited states, the “anomalous” increase in the angular function relaxation dynamics of the nuclei crucially Θ 0 within an angular range of ~ 130-140 , depends on the weak nuclear interaction.

  • CROSS SECTIONS of (N,P), (N,Α), (N,2N) REACTIONS on ISOTOPES
    CROSS SECTIONS OF (n, p), (n, α), (n, 2n) REACTIONS ON ISOTOPES OF Dy, Er, Yb AT En= 14.6 MEV А.O. Kadenko, O.M. Gorbachenko, V.A. Plujko, G.I. Primenko Nuclear Physics Department, Taras Shevchenko National University, Kyiv, Ukraine Abstract The cross sections of the neutron reactions at En= 14.6 MeV on the isotopes of Dy, Er, Yb with emission of neutrons, proton and alpha-particle were studied by the use of new experimental data and different theoretical approaches. New and improved experimental data were obtained by the neutron- activation technique. Present experimental results and evaluated nuclear data from EXFOR, TENDL, ENDF data libraries were compared with different systematics and calculations within codes of EMPIRE 3.0 and TALYS 1.2. Contribution of pre-equilibrium decay was studied. The recommendations on validity of different systematics for estimations of cross-sections of considered reactions are given. 1. Introduction Studies of the nuclear reaction cross sections induced by neutrons provides an opportunity to get information on the excited states of atomic nuclei and nuclear reaction mechanisms [1]. In addition, nuclear reaction cross section data are necessary in applied applications such as the design of fusion reactors protection and modernization of existing nuclear power plants [2, 3]. In particular, they allow to calculate the activity and the degree of radiation damage to structural elements of nuclear reactors [3]. Practical interest in cross sections of nuclear reactions caused by their wide use in experimental nuclear physics methods, such as the method of boundary indicators in measuring the spectrum of neutrons in the reactor core of a nuclear reactor, or neutron activation analysis.

  • Toxicological Profile for Tungsten
    TUNGSTEN 73 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY Tungsten is a naturally occurring element found in the earth=s surface rocks. Tungsten metal typically does not occur as the free element in nature. Of the more than 20 tungsten-bearing minerals, some of the commonly used commercial ones include feberite (iron tungstate), huebnerite (manganese tungstate), wolframite (iron-manganese tungstate), and scheelite (calcium tungstate). Tungsten appears in Group VIB of the periodic table. Natural tungsten is composed of five stable isotopes: 180W (0.12%), 182W (26.5%), 183W (14.3%), 184W (30.6%), and 186W (28.4%). Twenty-eight radioactive isotopes of tungsten are known; most of these isotopes have short half-lives. Tungsten forms a variety of different compounds, such as tungsten trioxide, tungsten carbide, and ammonium paratungstate (Penrice 1997a). Information regarding the chemical identity of elemental tungsten and tungsten compounds is located in Table 4-1. 4.2 PHYSICAL AND CHEMICAL PROPERTIES Tungsten has several common oxidation states (e.g., W[0], W[2+], W[3+], W[4+], W[5+], and W[6+]). However, tungsten alone has not been observed as a cation. Tungsten is stable, and therefore its most common valence state is +6. The naturally occurring isotopes of tungsten are 180 (0.135%), 182 (26.4%), 183 (14.4%), 184 (30.6%), and 186 (28.4%). Artificial radioactive isotopes of tungsten are 173–179, 181, 185, and 187–189 (O’Neil et al. 2001). Elemental tungsten metal is stable in dry air at room temperature. Above 400 °C, tungsten is susceptible to oxidation. Tungsten is resistant to many chemicals and is also a good electrical conductor (Penrice 1997a).

  • Abstract Ultracold Mixtures of Rubidium and Ytterbium
    ABSTRACT Title of dissertation: ULTRACOLD MIXTURES OF RUBIDIUM AND YTTERBIUM FOR OPEN QUANTUM SYSTEM ENGINEERING Creston David Herold, Doctor of Philosophy, 2014 Dissertation directed by: Dr. James Porto and Professor Steven Rolston Joint Quantum Institute, University of Maryland Department of Physics and National Institute of Standards and Technology Exquisite experimental control of quantum systems has led to sharp growth of basic quantum research in recent years. Controlling dissipation has been crucial in producing ultracold, trapped atomic samples. Recent theoretical work has suggested dissipation can be a useful tool for quantum state preparation. Controlling not only how a system interacts with a reservoir, but the ability to engineer the reservoir itself would be a powerful platform for open quantum system research. Toward this end, we have constructed an apparatus to study ultracold mixtures of rubidium (Rb) and ytterbium (Yb). We have developed a Rb-blind optical lattice at λzero = 423:018(7) nm, which will enable us to immerse a lattice of Yb atoms (the system) into a Rb BEC (superfluid reservoir). We have produced Bose-Einstein condensates of 170Yb and 174Yb, two of the five bosonic isotopes of Yb, which also has two fermionic isotopes. Flexible optical trapping of Rb and Yb was achieved with a two-color dipole trap of 532 and 1064 nm, and we observed thermalization in ultracold mixtures of Rb and Yb. Using the Rb-blind optical lattice, we measured very small light shifts of 87Rb BECs near the λzero wavelengths adjacent the 6p electronic states, through a coherent series of lattice pulses. The positions of the λzero wavelengths are sensitive to the electric dipole matrix elements between the 5s and 6p states, and we made the first experimental measurement of their strength.

Roederer4 and James E. Lawler5 Published in the Astrophysical Journal ABSTRACT We report the first detection of elements at all three r-process peaks in the metal-poor halo star HD 160617. These elements include arsenic and selenium, which have not been detected previously in halo stars, and the elements tellurium, osmium, iridium, and platinum, which have been detected previously. Absorption lines of these elements are found in archive observations made with the Space Telescope Imaging Spectrograph onboard the Hubble Space Telescope. We present up-to-date absolute atomic transition probabilities and complete line component patterns for these elements. Additional archival spectra of this star from several ground-based instruments allow us to derive abundances or upper limits of 45 elements in HD 160617, including 27 elements produced by neutron-capture reactions. The average abundances of the elements at the three r-process peaks are similar to the predicted solar system r-process residuals when scaled to the abundances in the rare earth element domain. This result for arsenic and selenium may be surprising in light of predictions that the production of the lightest r-process elements generally should be decoupled from the heavier r-process elements.

Shook and Donald Bogart Lewis Research Center SUMMARY Measurements of effective resonance integrals for separated tungsten isotopes en- riched in tungsten 182, 183, 184, and 186 and for natural tungsten were made relative to gold. The effective integrals were determined by using a small homogeneous reactor to measure epicadmium reactivities for samples of various sizes located at the center of the core. For comparison with the reactivity data, relative y-ray activities of cadmium- covered thin samples of gold were also determined. The experimental results were compared with effective resonance integral calcula- tions by using the Nordheim integral method and recently measured isotopic resonance parameters. Agreement between the calculations and experimental results for tungsten 182, 183, and 184 were generally good. However, for the tungsten 186 samples and for thick samples of natural tungsten, the calculations overestimated experimental effective integrals by 10 to 20 percent. For tungsten 186, the use of a radiation width of 44*4 millivolts for the highly scattering 18.8-electron-volt resonance brought calculations and experiment into better agreement. For natural tungsten, the experimental results indicated the presence of overlap effects for resonances of constituent isotopes.

  • Optical Frequency Measurement and Ground State Cooling of Single Trapped Yb+ Ions
    Optical frequency measurement and ground state cooling of single trapped Yb+ ions Peter Blythe March 2004 with updates and corrections August 2005 Submitted in partial ful¯lment of the requirements for the degree of Doctor of Philosophy of the University of London Abstract The thesis describes experiments on single laser-cooled ions of Yb+ in a radiofrequency ion trap. 2 2 The ion is laser-cooled on the 369 nm S1=2! P1=2 electric dipole tran- 2 2 sition, and high resolution spectroscopy of the 467 nm S1=2! F7=2 electric octupole `clock' transition has been performed. The 467 nm transition can be used as an optical frequency standard. To this end, several absolute optical frequency measurements of the F = 171 + 0; mF = 0 ! F = 3; mF = 0 component in Yb have been made with a femtosecond laser frequency comb generator. The comb was referenced to a hydrogen maser which forms part of the clock ensemble used to generate the UTC(NPL) timescale. During the work described in this thesis, the linewidth of the 467 nm probe laser has been narrowed from 4 kHz to 200 Hz, increasing the measurement resolution. The frequency measurements have been supported by a full investigation of the systematic frequency shifts of the octupole transition, including the AC Stark, second-order Zeeman, quadrupole, DC Stark, second-order Doppler and blackbody shifts. Cooling an ion of 172Yb+ to the ground motional state of the ion trap by `EIT cooling' on the 369 nm transition has been investigated, both by numerical simulation and experiment. A new technique for measuring the temperature of a trapped ion without the use of a narrow transition has been developed.
